Employee and Production Worker Classes C++

Employee and ProductionWorker Classes
Design a C++ class named Employee. The class should keep the following information in
member variables:
• Employee name
• Employee number
• Hire date
Write one or more constructors and the appropriate accessor and mutator functions
for the class.
Next, write a class named ProductionWorker that is derived from the Employee
class. The ProductionWorker class should have member variables to hold the following
information:
• Shift (an integer)
• Hourly pay rate (a double)
The workday is divided into two shifts: day and night. The shift variable will hold an
integer value representing the shift that the employee works. The day shift is shift 1
and the night shift is shift 2. Write one or more constructors and the appropriate
accessor and mutator functions for the class. Demonstrate the classes by writing a
program that uses a ProductionWorker object.

Answer:

Employee and ProductionWorker classes

#include <iostream>
#include <iomanip>
#include "ProductionWorker.h"
using namespace std;

// Function prototype
void displayInfo(ProductionWorker);

int main()
{
	ProductionWorker pw("John Jones", "123", "1/1/2006", 2, 18.00);
	displayInfo(pw);
	return 0;
}

//******************************************************
// The displayInfo function displays a production      *
// worker's employment information.                    *
//******************************************************
void displayInfo(ProductionWorker e)
{
	cout << setprecision(2) << fixed << showpoint;
	cout << "Name: " 
		 << e.getName() << endl;
	cout << "Employee number: " 
		 << e.getNumber() << endl;
	cout << "Hire date: " 
		 << e.getHireDate() << endl;
	cout << "Shift: " 
		 << e.getShiftName() << endl;
	cout << "Shift number: " 
		 << e.getShiftNumber() << endl;
	cout << "Pay rate: " 
		 << e.getPayRate() << endl;
}
